Why does black paint dry quicker than white?

Question

Why does black paint dry quicker than white paint?
Youll, Beckenham

Answer

** Definitive **
Name: Philip, Stevenage
Qualification: Chartered Engineer in Thermodynamics
Answer: The colour white reflects heat, which is why houses and roads are often painted white in tropical regions. Black absorbs heat, but it also radiates heat, which doubly helps the drying process.
